Closed mdurling closed 7 years ago
Thanks for the heads-up. I haven't yet tried 2.3.2
.
You opened this issue in bootstrapper-webpack
, is this what you're using?
You should use regular aurelia-bootstrapper
, it was made "universal" a while ago and bootstrapper-webpack
only exists as to not break existing builds.
We are using aurelia-bootstrapper-webpack@1.1.0
and including it in the core bundle. We originally created our application from aurelia/skeleton-navigation
and it is used there.
I did update all the demos in my repo to webpack 2.3.2
and I did not have any issue, so for what it's worth I think that our latest Webpack plugins / runtime do work properly.
@mdurling you are using older stuff that I am not familiar with, so hopefully someone else can chime in here.
Perhaps you could send me a copy of or a link to the webpack.config you used and your package.json? I can see if we're doing something outdated. Thanks.
It's not just a version upgrade, it's redesigned Webpack plugins so you'll need to do a few changes to your build and your code.
If you are interested in upgrading I suggest you start by reading about the new plugins here: https://github.com/jods4/aurelia-webpack-build/wiki
There are several working demos config in that repo as well, I just upgraded all of them to Webpack 2.3.2.
@jods4 @EisenbergEffect I am making good progress converting our application over to the new plugins/runtime. I've replaced aurelia-bootstrapper-webpack
with aurelia-bootstrapper
, updated to the latest webpack
and added all of the necessary PLATFORM.moduleName
calls. The application now builds, starts, runs some of our code, but then throws the following exception. Can you provide any insight into what might still be wrong?

This is where things start to go wrong:
@mdurling doesn't look related to webpack (DI rather) but reminds me a lot of aurelia/pal-browser#17.
Do you have a custom boot sequence?
If yes, you must absolutely ensure that aurelia-pal-browser
is initialized before any other lib that might use the PAL, aurelia-framework
in particular.
aurelia-bootstrapper
does this right.
This sounds like it may be related. I'm not sure what you mean by "custom boot sequence" but it's quite probable that we do. On Sat, Apr 1, 2017 at 12:44 PM jods notifications@github.com wrote:

I mean that the basic way to start Aurelia is to import aurelia-bootstrapper
and let it flow from here.
If you load other stuff before that involving Aurelia, it's tricky.
I added import aurelia-bootstrapper to the top of my main.ts, but that didn't change anything.

Well, there is a lot here.
You're entry point is aurelia-bootstrapper
so that's good.
I am not familiar with @easy-webpack
I have some doubts regarding how you build your common/vendor bundles, though. Which file do you load in your HTML index page?
I am wary of your aurelia
chunk, because if you load it, then all those modules you have listed are entry points and they will all get executed when this file is loaded. Executing aurelia-framework
before aurelia-pal
is initialized (and unfortunately this is different from just importing it, see the related issue) is known to create this bug.
This comment might be relevant.
Thanks. I think I understand how this is supposed to work now and have made some progress. Based on your suggestions, I removed all of the bundling and now have just a single entry aurelia-bootstrapper
. I am no longer getting that DI error. The app loads, but now it is throwing an exception because it can't find the module for the initial route even though all of the routes are defined using PLATFORM.moduleName()
just like app root, features, globalResources, etc. are which are being found/loaded.
It looks like most of my source files are not being bundled... This is the tail of the webpack --display-modules

My routes appear nowhere in the list. I would expect them at the end with the rest of the named modules, but they're not even in the number modules!
@jods4 I figured out what was happening. Our route configs are build up functionally and the PLATFORM.moduleName
was being called within a function. This makes sense programmatically, but not when you consider that the webpack plugin needs to parse for these things during the build. I moved the PLATFORM.moduleName
to where the moduleId
string is declared and now it works. Thank you so much for your guidance in getting me to this point. This approach is much more intuitive than the old webpack plugin.
A few other items that I would like your opinion on if you don't mind.
The output.filename
property seems to have no affect on the generated bundle. I am getting main.bundle.js
regardless of the output.filename
setting. I am assuming something else in my config is overwriting it, but I'm not sure. It's not a problem for now, but I think I need to figure it out before I will be able to get any sort of code splitting to work.
What is your recommended approach to bundling vendor modules. Is the ReferenceDll plugin the easiest way to go and just build the vendor module separately?
What is your recommended approach for handling polyfills? Should they just be put in the main entry along with aurelia-bootstrapper
, or should they be bundled separately?
I get a couple of strange errors when running our unit tests in karma:

I am glad I've invested the time to convert our project over. I like the new bootstrap approach much better. Thanks again.
Glad you figured it out!
As for your questions:
I don't know what happens exactly as your config is complex and uses a lot of easy-webpack
magic that I'm not familiar with.
output.filename
is what drives the output and FWIW Aurelia plugin 2.0 does not touch this setting.
Have a look at the doc: https://webpack.js.org/configuration/output/#output-filename, if you have more than one entry point you need to use some patterns.
It kinds of depends on what your goal is. Currently there are 2 main options: ReferenceDll
and CommonChunks
but they have very different trade-offs.
DLL is more complex and disables lots of (size) optimizations (like tree-shaking, exports renaming and more) but it allows for true split compilation (hence faster) and long-term caching.
Commons chunk is simpler but -- if we are talking about a vendor bundle and not its true purpose which is putting common modules in separate bundles -- is only good for having parallel downloads at startup and faster HMR.
Both works with Aurelia plugin, but if you go for the latter I have two advices: (a) you don't need to list everything... dependencies are transitively brought in, so aurelia-bootstrapper
will already bring all the core in the bundle; (b) put the "commons" in a new chunk and include that one in your page, not the vendor
entry. As explained above, if you include vendor
then all you've listed as entry points will execute and at the moment this triggers the DI bug.
More info about DLL if you intent to use is: https://github.com/jods4/aurelia-webpack-build/wiki/Using-Webpack-DLL
I am thinking about this at the moment. I think I will do a plugin to help as well. The tricky part with polyfills is that they have to execute before anything else, at least if they are required by Aurelia itself (e.g. Promise, MutationObserver, ...). And that is more tricky then it looks.
One easy way to handle it is to have one bundle with all your polyfills as entry points, and putting that first in the HTML page.
Please note that Aurelia injects some stuff in your main entry point, if you have several it assumes that it is the first one, otherwise you can pass entry: "name"
to clarify.
The first error is not telling a lot. The second is more concerning, it seems that aurelia-loader-webpack
is not used. Normally it's added automatically to your app entry point (see 3). I am not sure how you build your tests / what happens here.
Update: I have everything working now. After experimenting with various common chunks scenarios which I eventually got to work, I decided the benefit wasn't worth the maintenance overhead. I had to sort the entry points manually because we are using an ejs template and a webpack plugin to generate our index.html file and then exclude the bundle containing the code I don't need. It's just so much simpler to use aurelia-bootstrapper as the lone entry point. All the extra bundle really does is move the bytes around anyway. As for bundle size, I can accomplish the same thing much easier by just using webpack externals. As for my unit tests, I was able to get rid of those errors by pointing the aureliaApp at my spec file instead of main and loading aurelia-polyfills. Thanks again for all of your guidance. While it took me a while to get everything sorted, it was worth the effort. I even tested the Aurelia code splitting feature and it works great too! @eisenbergeffect we're loving Aurelia and the support your team provides. @jods4 went above and beyond.
@jods4 We have one component that is rather large. It is currently being loaded as follows:
config.globalResources([
PLATFORM.moduleName('resources/components/foo')
])
This Aurelia component is a wrapper around a ReactJS component and consists of a single foo.tsx
file and uses @noView
. I have been trying to figure out how to bundle this component separately so that it is lazy loaded, but I have so far been unsuccessful. If I remove the call to globalResources
then the code isn't loaded into the app bundle, but adding it to the aurelia.resources
section of our package.json
file does not cause a separate bundle to get created. I have tried adding the <require>
statement back to the view that uses this component both with and without the lazy
attribute, but I either get the component included in the app bundle or not at all. I am not sure if the .tsx
extension is somehow causing an issue or if I am just doing something incorrectly. I can probably use the common chunks plugin to force webpack to put this component in its own bundle, but that won't accomplish the lazy loading. Any advice you can provide would be appreciated. Thanks!
aurelia.resources
ain't used by the new plugins, it's only there for the 1.x users.
lazy
on <require>
is not supported either, as I have yet to find a scenario where it would make sense.
When you load the view, Aurelia has to load the <require>
so splitting code here makes no sense.
I am assuming that you are not just after creating multiple files but lazy-loading on-demand for just the routes that need it.
Here's how to do it:
<require>
. The problem of .globalResources()
is that it's immediately loaded at startup so there's no use making a split point here.moduleName
is an optional chunk name, so in your routes config do something like:
module: PLATFORM.moduleName('module-that-use-react', 'arbitrary-chunk-name')
.Because dependencies are precisely traced, the <require>
'd component will go along with the view.
@jods4 Thanks for the reply. That matches what I have found. I was able to get the global resource into its own chunk, but it was being loaded at startup which defeated the whole purpose. I removed it from the global resources, added a local resource require, and added a chunk name to the route that is using it and I get the desired behavior. Thanks again. It would be good at some point to update the Webpack section of the docs at aurelia.io as they still describe the old manner of using Webpack. The new plugins and runtime have been working great for us since making the switch. Cheers, Michael
@mdurling Could you give an example of how you got your unit tests working. I am getting the same platform.loader issue you mentioned above?
@narmstrong1988 Are you doing a require('aurelia-bootstrapper')
in your spec-bundle
file? In our setup, I fixed the error messages by replacing require('aurelia-bootstrapper')
with require('aurelia-polyfills')
but it likely depends on how you are creating your spec bundle. Our tests were passing in both cases, but the latter eliminated the errors we were seeing in the logs. Hope this is helpful.
I have a small Aurelia app and just upgraded Webpack to version 3 without any code changes. The app fails to load with this message:
Uncaught (in promise) No PLATFORM.Loader is defined and there is neither a System API (ES6) or a Require API (AMD) globally available to load your app.
Update: I upgraded html-webpack-plugin to 2.29.0 - the latest at this time - and all is back to normal.
We have an Aurelia app that works fine when built with
webpack@2.2.1
, however, it will not load when built withwebpack@2.3.2
. Have you done any verification with the latest webpack release? We are reverting to 2.2.1 for now, but here is the error that is generated when running the latest webpack build:
